Quizplus · Accepted Answer

The vertical shift (or vertical displacement) is the value added or subtracted to the sinusoidal function to shift it up or down. In this case, the y-intercept or vertical shift is 320, implying that the graph is shifted 320 units up from its original position. Therefore, the correct choice is C.
